Abstract: A method and apparatus for providing active termination of a transmission line is accomplished by providing a pair of complementary transistors operably coupled to the transmission line, wherein one of the transistors provides the active termination impedance when the transmission line is in a first state, and the other transistor provides the active termination when the transistor is in a second state. The complementary pair of transistors may be gated such that when it is desired to remove the active termination from the circuit, it can be done. The line driver/receiver reduces part count by commonly using circuitry in the active termination stage and the receiver stage.
